T0 @Uu/hom, it .may concern:

Be it known thatLfFREDERICK K. CHRIS- TENSEN, a citizen of the UnitedStates, residing at Sandy, in the county of Salt Lake, Stateof Utah,have invented certain new and useful Improvementsin Vehicle-Tires and Ido hereby declare the following to beafull, clear, and exact descriptionof the invention, l

such as will enable others skilled inthe art to whichit appertains tomake and use the same.

This invention relates to vehicle-tires; and it has for its object toprovide a tire of that class known-as armored tires the construction ofwhich will be such as to prevent puncture of the air-,tubeand which alsowill prevent slipping of the tire both laterally and circumferentially.

Other objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this specication, and in which likenumerals of reference indicate similar parts in the several views,Figure lis a perspective view showing a section of thearmor. through atire in a plane at right angles to the axis thereof. Fig.' 3is asectiontransversely through a tire embodying the present invention. f

.Referring now tothe drawings, the armor of the present tire consists ofa continuous band 5, which is transversely arc-shaped and disposed uponthe air-tube 6, of rubberor other similar material. vided upon its outeror convexface with a plurality of ribs 7,which extend transversely ofthe band'and decrease gradually in'height f from the central line of theband` in the direction of the side edges thereof. The central portion ofeach of the ribs has a knifeedge, while the end portions of the ribs areiiattened, as illustrated.A -Y

Fig. 2 is a section Spaced laterally from the center line of the band 5and against the outer face thereof are secured'or formed thelongitudinal ribs 8 and 9, extending circumferentially of the band,theedges of these ribs being sharpened and lying'below the lineconnecting the central points of the edges ofthe transverse ribs, sothat the longitudinal or circumferential ribs do notv touch the groundwhen thel tire stands in a vertical plane. With this construction itwill be seen that 'the transverse ribs will give the required frictionto' prevent slipping of a drive wheel circumferentially, while when thewheel is tilted, aswhen turning, either of the circumferential ribs willcome in contact with the ground, depending upon the direction in whichthe wheel is tilted, and lateral slipping of the wheel will beprevented.

In the central portion of each of the transverse ribs is formed a groove10,the' grooves of the several ribsof the band beingin alinementcircumferentially ofthe tire.

' What is claimed is- In a tire, the combination with theair.tube, of anarmor secured thereto, said armor have ing transverse ribs havingalining slots through their central portions, and-circum ferential ribsspaced lat'eally`from`the central line of the tire, the circumferentialribs projecting beyond the transverse ribs at the points upon thel armorat which they lie and lying inwardly of the tire :from the middle,portions of 'the transverse'ribs.

In testimony whereof I affix my signature in presence` of j twowitnesses.

FREDERICK K. CHRISTENSEN.
